If you can route a shorter belt and do away with the smog pump altogether I would go with that. Otherwise the pumps usually have the main housing with a cover plate bolted to it. You need to get access to the inside of the pump, remove the internals, so that it is not pumping all time.
Pump Type: The first system known as the Pump Type includes an air pump, commonly known as the smog pump, which is responsible for supplying fresh pressurized oxygen to the exhaust stream through header or exhaust manifold, and/or before the Catalytic Converter.f your vehicle is equipped with a pump air injection system the technician will be checking for the proper connection of the injection system plumbing, all hoses, lines, valves and smog pump. The smog technician will also examine the air pump belt for proper tension and damage.
